We want to empower girls and young people that have periods as well all those around them to be period proud, so join the movement and let's normalise periods together."
Don't bleed but want to support?" has been changed to "Don't have periods but want to support?",
I'm all for people recognising that periods are part of the normal female life cycle and removing stigma. But personally I've never felt a desire to be "period proud" and I can't say I would welcome "support" from random men or whoever those supporters are that don't bleed.
I really think most women and girls prefer a little privacy. It feels like going from one extreme to the other.
